Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a method for integrating roof sleeves with the roof surface during construction. Background Technology

[0002] In waterproofing weak points of roof sleeves, traditional construction methods (relying solely on rolled-up membrane and mortar sealing) often lead to leaks at the sleeve base due to loose waterproofing layer connections, material aging, or improper construction. This is especially true in environments where roofs are constantly exposed to ultraviolet radiation, temperature differences, and rainwater erosion, making the waterproofing layer at the sleeve base prone to failure. According to industry statistics, leaks at the sleeve location account for approximately 30%-40% of roof leaks, severely impacting the building's functionality and durability. Summary of the Invention

[0003] To address the aforementioned issues, a method for integrating roof sleeves with the roof surface is proposed, aiming to reduce maintenance frequency and costs, create long-term economic benefits for the project, and enhance the asset value of the building.

[0004] The specific technical solution is as follows: The method of integrating roof sleeves with the roof during construction includes: According to the dimensions of the pipes extending from the floor to the roof, steel sleeves are made, and then water-stop rings are welded onto the steel sleeves. The surface of the water-stop rings is roughened, and then micro-protruding teeth are set on the outer edge of the water-stop rings. According to the drawings, locate the position of the pipes passing through the roof, pre-embed steel sleeves, fix them firmly, and after acceptance, pour roof concrete to form the first waterproof barrier. Clean the base of the steel sleeve and the surrounding base layer, and round the inside corner where the steel sleeve intersects with the roof. After the base layer is cleaned, a layer of waterproof coating is applied to the base layer around the casing root and then a fiberglass mesh is laid. The first waterproof membrane is then covered on the fiberglass mesh as an additional layer to ensure a seamless connection between the base layer around the steel casing and the waterproof membrane. After cleaning the surface of the waterproof membrane, apply adhesive and install the waterproof gasket; Lay at least two layers of second waterproof membrane as a second waterproof layer to cover the waterproof gasket and the area around the steel sleeve. After turning the first and second waterproof membranes up, apply sealant and then wrap and tighten the first and second waterproof membranes around the steel sleeve. Fine aggregate concrete is poured around the steel casing to form a protective wall; Install a conical cover on the top of the steel casing.

[0005] Furthermore, the cleaning range of the base layer around the steel casing is 400-600 mm.

[0006] Furthermore, the inside corner where the steel sleeve intersects with the roof is rounded with cement mortar.

[0007] Furthermore, one side of the waterproof gasket has a wavy textured surface, with the textured surface facing downwards during installation.

[0008] Furthermore, after installing the waterproof gasket, use a pressure roller to compact it to ensure that the waterproof gasket does not slip.

[0009] Furthermore, the waterproof membrane is flipped up to a height of 200-300 mm, and adjacent waterproof membranes are bonded together by hot-melt bonding, with an overlap width of 100-130 mm.

[0010] Furthermore, the inside corner where the concrete retaining wall intersects with the steel sleeve is sealed with sealant.

[0011] Furthermore, galvanized iron wire is used to wrap and tighten the waterproof membrane onto the steel sleeve.

[0012] Furthermore, the lower end of the conical cover extends at least 40 mm below the inside corner formed by the junction of the fine aggregate concrete retaining wall and the outer wall of the steel sleeve.

[0013] Furthermore, the sealant application width is 9-12 mm.

[0014] The beneficial effects of the above scheme are: 1) Traditional sleeves are mostly single-ring waterproofing sleeves, which are prone to detaching from the concrete. This invention designs a ring-type sleeve with a roughened surface and micro-protruding teeth on the outer edge, allowing for better embedding into the concrete structure layer, enhancing the bonding force with the concrete, and preventing water from flowing along the ring surface to form the first deep waterproofing barrier. This ring-type sleeve overcomes the instability of traditional single-ring sleeves and improves the fit between the ring and the concrete. 2) The surface of the waterproof gasket is decorated with wavy textured grooves. It is installed on the waterproof layer and heat-fused to the overall waterproof layer, increasing the bonding contact area with the upper and lower layers and forming a second waterproof barrier. 3) The composite waterproof layer structure provided in this invention includes a waterproof coating (flexible layer), a fiberglass mesh (reinforcing layer), and a thin SBS waterproof membrane (additional protective layer). The flexible layer adapts to deformation, and the mesh provides tensile strength. This composite waterproof layer structure can serve as a basic waterproof barrier. Attached Figure Description

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the scope of the invention.

[0019] like Figure 1 As shown, the integrated construction method for roof sleeve and roof provided in the embodiments of the present invention includes: According to the dimensions of the pipes extending from the roof, a steel sleeve 2 is made, and then a water-stop ring 3 is welded onto the steel sleeve. The surface of the water-stop ring is roughened (width 50 mm, thickness 4 mm, stainless steel, Ra≥50 μm). Micro-protrusion teeth (height 2 mm, spacing 5 mm) are then set on the outer edge of the water-stop ring. According to the drawings, locate the position of the pipe 1 through the roof, pre-embed the steel sleeve 2, fix it firmly, and after acceptance, pour the roof concrete to form the first waterproof barrier. Clean the base of steel sleeve 2 and the surrounding 500 mm area, and round the inside corner where steel sleeve 2 intersects with the roof with cement mortar; After the base layer is cleaned, apply a 1.5 mm thick polyurethane waterproof coating to the base layer at the root of the steel sleeve 2 and around it, then lay a 5 mm*5 mm fiberglass mesh 13 (pressed flat without wrinkles), and then cover the fiberglass mesh with a 1.5 mm thick thin SBS waterproof membrane as an additional layer 4 (hot melt bonding, turned up 250 mm, overlap width 120 mm) to ensure that the base layer around the steel sleeve 2 is seamlessly connected to the waterproof membrane. Clean the surface of the waterproof membrane, remove dust, apply 0.5 mm thick EPDM special adhesive, install waterproof gasket 6 (one side of the waterproof gasket 6 has a wavy texture with a wave height of 1 mm, and the texture should face down during installation), and press the waterproof gasket 6 tightly against the base of the steel sleeve 2. Use a pressure roller to compact it for 30 minutes to ensure that there is no slippage. Two layers of 1.5 mm thick SBS waterproof membrane are laid as the second waterproof layer 5 (hot melt bonding, turned up 250 mm, overlap width 120 mm) to cover the waterproof gasket 6 and the area around the steel sleeve 2 within 500 mm. A 10 mm wide sealant is applied to the 250 mm upturn of the SBS waterproof membrane, and the first and second waterproof membranes are wrapped and tightened to the steel sleeve 2 with φ1.2 galvanized iron wire 12. A 30 mm (thinnest part) fine aggregate concrete was poured around the steel sleeve 2 to form a protective wall 8; The inside corner where the concrete retaining wall 8 intersects with the steel sleeve 2 is sealed with sealant 7. A conical cover 11 is installed on the top of the steel sleeve 2, and the lower end of the conical cover 11 covers at least 40mm below the inside corner formed by the junction of the retaining wall 8 and the outer wall of the steel sleeve 2.

[0020] Traditional water-stop sleeves are mostly designed with a single water-stop ring, which is prone to detaching from the concrete. This invention designs a water-stop ring sleeve. The surface of the water-stop ring 3 on this sleeve is roughened, and the outer edge has micro-protruding teeth, thereby better embedding into the concrete structural layer, enhancing the interlocking force with the concrete, and preventing water from flowing along the surface of the water-stop ring to form the first deep waterproof barrier. This water-stop ring sleeve overcomes the shortcomings of the traditional single water-stop ring sleeve in terms of unstable effect, while also improving the fit between the water-stop ring and the concrete.

[0021] In this invention, the surface of the waterproof gasket 6 is provided with a wavy texture. It is installed on the waterproof layer and is thermally bonded to the waterproof layer as a whole, which increases the bonding contact area with the upper and lower layers. The gasket is placed in the middle and is protected by the overall waterproof layer, which reduces the direct erosion of ultraviolet rays, rainwater and temperature difference, extends its service life, enhances the sealing performance of the joint, improves the durability of the waterproof layer, and forms a second waterproof barrier.

[0022] The composite waterproof layer structure provided in this invention includes a waterproof coating (flexible layer), a fiberglass mesh (reinforcing layer), and a thin SBS waterproof membrane (additional protective layer). The flexible layer adapts to deformation, and the mesh provides tensile strength. This composite waterproof layer structure can serve as a basic waterproof barrier.

[0023] After the waterproofing construction is completed in this invention, the insulation layer 9 and the concrete protective layer 10 on top of it can be constructed subsequently.

[0024] The above description is merely a preferred embodiment of the present invention and does not limit the implementation and protection scope of the present invention. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
